It suffices to show the map π is injective, since for *-morphisms of C*-algebras injective implies isometric. Let x be a non-zero element of A. Witrynathe Naimark theorem.

Original statement of Naimark

WitrynaGelfand and Naimark were using functional analytic methods as tools in their analysis. In 1967 Stein constructed, in a fairly simple manner, representations in GL(2«, C)" which were not contained in the lists of Gelfand and Naimark [St]. For some other classical groups, it was even easier to see the incompleteness of the lists from [GfN2].
